5-year geometric mean of smoothed wild spawners
5-year geometric mean of smoothed wild spawner estimate (smoothed total spawners times smoothed fracwild). In parentheses, the 5-year geometric mean of smoothed total spawners (black thick line in graphs) is shown. A row with only values in parentheses indicates that no fraction wild estimates were available for that population. Geometric mean was computed as the product of counts raised to the power 1/(number of values in band). Percent change between the most recent two 5-year periods is shown on the far right.

5-year geometric mean of raw wild spawners
5-year geometric mean of raw wild spawner counts. This is the raw total spawner count times the fraction wild estimate, if available. In parentheses, 5-year geometric mean of raw total spawner counts is shown. A value only in parentheses means that a total spawner count was available but no or only one estimate of wild spawners available. The geometric mean was computed as the product of counts raised to the power 1 over the number of counts available (2 to 5). A minimum of 2 values were used to compute the geometric mean. Percent change between the most recent two 5-year periods is shown on the far right.

15-year trends
15-year trends (slope) in log wild spawner abundance computed from a linear regression applied to the smoothed wild spawner log abundance estimate versus year. In parentheses are the upper and lower 95% CIs. Only populations with at least 4 wild spawner estimates and with at least 2 data points in the first 5 years and last 5 years of the 15-year ranges are shown.
